Letters .Patent No. 95,949, dated October 19, 1869.

COAL-STOVE.

The Schedule referred to in these Letters Patent and making part of the name.

To all whom 'it may concern Be it known th'at I, H. STICKNEY, of Cleveland, in the county'of' Cuyahoga, and State of Ohio, have ini vented a new and improved Heater; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled ,in the art to-make and use the-same, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to improvements in baseburning heaters, having forits object to provide certain improvements in the construction and arrangement of the base, and in the application of water-vessels around 'by` the action of the feed-door in opening, to prevent the escape of gas, when supplying the magazine.

Figure 1 represents a sectional elevation of my improved heater;

higure 2 Yrepresents a planet' the grate and the base; and

Figure 3 represents a detail, showing a. modified arrangement of self-actin g valve, adapted for vertical magaznres.

Similar let-ters of reference indirette corresponding parts.

The base A, surrounding the ash-pit B, is made large'and conical, furnishing a reston the inclined sides thereof, for the water-vessels C.

This water-vessel surrounds the enclosure containing the ire, and prevents the same from -burning out by -the intense :heat to which Vit is subjected, absorbingand transmitting the heat therefrom as it radiates in that direction.Y

- D represents the grate, which is iixed, and provided With a central opening, E, and radial-openings F, and above it a stirrer, G, is placed, which is made to oscillate over the plate D and the openings therein',.by a crank, H, below, connected to the central stem of the stirrer and a connecting-rod, I, which is provided with an eye, K, at the outer end, through which a lever or poker, 14,'may be placed, and engaged with a holder at the bottom, so as to have greater leverage in working the stirrer.

Above the re-pot M,'I arrange a radiating-drum, N, through which the products of combustion pass.

The walls of this drum. resemble in form a.- series of sections of cones, superposed upon each other', the cones of the outer wall being inverted.

This arrangement provides a great amount of heating-surface. Any number-of conical sections may be used, and the drum extended vertically, more or less, as required.

The magazine is designed to be made vwith a joint at Q, for the introduction of extension-pipe, to lengthen it with the drums when required.

R represents a-self-closing valve, placed yin the magazine, to prevent the escape yof gas, and so arranged as to b e openedlby the coal when poured in.

In iig. 3, R' represents another' self-closing arrangement of magazinervalvessuch as I design to use when the magazine rises vertically Ato the top. In this casek the valve is hingedto a plate, S, `projecting from one side, closing a part of the passage, and protecting the weighted arm T from the coal.

I propose to attach a connecting-rod, U, to :the draught-door V, below, arranged to suspend the said door from the catch W, of, the magazine-door X, so that when the latter is` opened 'it will disconnect the suspending rod, and allow the draught-door V to close -while' the magazine is being supplied,'whereby an inward draught will be induced at the magazine-door, andthe 'gas thereby prevented from escaping while supplying fresh coal. Y

Having thus described my invention,

I claim as new, and desire to'secure by Letters Patent- 1. The arrangement, in a heater and about the magazine, of the radiator N, surrounding the reserv"oir P, and formed of twol conical frusta, but having the respective bases thereof reversed, all as shown and described.

2. The combination of a iire-pot, M, and stirrer G,

rod I, and operating lever L, when arranged substantially as specified.

4. The combination of the `draught-door V, magazine-door 1X, catch W, and connecting-rod U, when arranged for causing the draught-door to be disc9n nected from the suspending catch, for closing the same by the action of the magazine-door, when opened, all substantiall y as specified.

H. STICKNEY.
